Standard and Protrader Graphs
When backtesting, I would like to be able to look at graphs as they looked on the day they appear on unisearch or on a portfolio. I would then be able to 'cherry pick' which stocks meet the overall chart patterns I am looking for. As it stands, the portfolio will look for stocks that match your criteria, and you need to buy the top ones. Being able to view the chart on that day would enable you to either accept or reject each stock as you see fit.

I see you can do exactly this with the custom date. I'll look at the other suggestions to see where I can use my votes.
